Frequently Asked Questions - RG3-15CLS ENTES

How do I set the target power factor (Cosφ)?

Press the SET button for 3 seconds to enter the menu. Use UP/DOWN to find the 'COS' or 'COS2' menu. Press SET, then use UP/DOWN to adjust the value between -0.800 (capacitive) and 0.800 (inductive). Press SET to confirm. Exit by pressing ESC until 'SAVE SET yES' appears, then press SET to save.

What does the alarm LED indicate and how do I reset alarms?

The alarm LED lights up when a fault occurs, and an error code is displayed. To reset alarms, go to the menu by pressing SET for 3 seconds, find 'rESEt' menu, then 'ALAr'. Select 'yES' to clear alarms. If the fault persists, the alarm will reactivate.

How many capacitor steps can the RG3-15CLS control?

The RG3-15CLS controls up to 12 capacitor steps. The last step number can be set between 1 and 12 in the 'StEP' menu. Steps beyond the set number are disabled.

What are the switching sequences available?

There are 10 program sequences (PS-01 to PS-10). PS-10 is recommended as it automatically calculates step powers and optimizes switching. Other sequences use fixed ratios based on the first step power.

How do I connect the device properly?

Ensure 3-phase neutral connection for auxiliary supply, voltage, and current. Connect a 3-phase capacitor to step 1. Single or 3-phase capacitors can be connected to other steps. Use FF type fuses (2A/3A for control, 6A for capacitors). Refer to the connection diagram in the manual.

What does error code 'Error-07' mean?

Error-07 indicates that the voltage value of any phase exceeds the preset overvoltage limit. Check the system voltage and the overvoltage setting in the alarm menu (ALr). The overvoltage LED (V>) will also be lit.

Can I use the device with a generator?

Yes. Connect the generator input (110-250 VAC) such that the signal appears only after the generator is connected. The device then switches to target Cosφ2 and compensates accordingly. When the generator signal disappears, it reverts to target Cosφ.

How do I perform automatic capacitor recognition?

After first energization, the device auto-corrects connections. Then, in the 'Auto Operati' menu, set 'Auto Setup' to 'on'. The device measures step powers based on the selected program. For accurate results, ensure CT and VT ratios are set correctly and variable loads are disconnected.

What is the purpose of the C+, Normal, and C- LEDs?

C+ indicates the device is waiting to switch on capacitor steps. C- indicates waiting to switch off. Normal means no switching action is required. These LEDs help monitor the compensation status.

How do I clean and maintain the device?

Use only a dry cloth to clean the front panel. Do not use solvents or water. Maintenance, installation, and operation must be performed by qualified electricians. Do not open the housing; there are no user-serviceable parts inside.

Consult the operating instructions before using the equipment. Following these precautions is a must for an error-free operation and maintaining the eligibility for a warranty.

Therefore, please read this manual carefully before commissioning and using the RG3-12C/CS.

Precautions for Safe Use and Installation

1) Maintenance, installation and operation of RG3-12C/CS must be performed only by the qualified electricians.
2) Do not operate the device in undervoltage conditions.
3) Do not open the RG3-12C/CS's housing. There are no user servicable parts inside it.
4) RG3-12C/CS is connected to the network by means of a current transformer. Do not disconnect the current transformer terminals. If you disconnect them, be sure to short-circuit the terminals or connect them to another parallel load which has a low impedance. Otherwise, dangerously high voltage at the secondary side of current transformer may cause an electric shock.
5) Do not use this product for any other purpose than its original task.
6) When device is connected to the network, do not remove the front panel.
7) Do not clean the device with solvent or similar items. Only clean with a dried cloth.
8) Verify terminal connections before commissioning.
9) Electrical equipment should be serviced only by your competent seller.
10) Device is only suitable for panel mounting.

No responsibility is assured by the manufacturer or any of its subsidiaries for any consequences rising out of disregarding these precautions while handling the RG3-12C/CS.

Important Note for System Connection.

1) First, connection type of auxiliary supply, voltage measurement and current measurement input must be neutral. The device will not operate properly if these connections are not done.
2) A 3-phase capacitor must always be connected to the first step. Providing that this connection is followed for the first capacitor step, 3-phase or single phase capacitor banks can be connected to the other steps in any order according to your systems needs.

Do not energise the device before verifying terminal connections.

Generator Input Connection

The connection to the generator input of the device must be done in a way that the energy comes to the system after the generator connection to the network has been established. Otherwise, the device will switch to generator mode when the generator is started for maintenance purposes.

If there is a voltage between 110-250 VAC present on the generator inputs of the device, the target “Cosφ” set on the device is deactivated and target “Cosφ2” is activated. Then the device starts the compensation according to target Cosφ2. This operation mode continues until the voltage on the generator input is disappeared.

Monitoring the measured temperature

In order to make a correct measurement, J type (Fe/Cu-Ni) thermocouple must be connected to "TEMP" terminal and keep worked at least 30 min. In order to observing the measured environmental temperature, press UP/DOWN buttons until the displaying the "xxx.x °C" value.

NOTE: RG3-12C/CS temperature measurement feature is optional.

In todays world, the reactive loads on a network continue to increase with the contracted power rise. The increase of the power on transformers, transmission lines and generators caused a rise in the reactive power levels just as much and maybe more than the active power levels. To prevent any overloads and under voltage conditions, the compensation of the reactive loads became a necessity in todays energy network.

Power factor controllers monitor the reactive power of a plant and try to match the power factor value which is defined as the ratio of the active power(W) to the apparent power(VA) to a power factor value which is defined on the device by the user.

RG3-12C/CS power factor controller is designed for reactive power compensation in single phase and 3-phase systems.

RG3-12C/CS compensates each phase separately and so, this makes RG3-12C/CS series a unique solution for unbalanced load compensation. In order to achieve this feat, single phase and 3-phase capacitor steps must be connected to the device at the same time.

CONNECTION DIAGRAM

* Current value of 3-Phase fuses, which are connected to protect the capacitors, must be chosen according to the nominal current value of capacitors which are given by the manufacturer.
**Optional.

Warnings :

a) First, connection type of auxiliary supply, voltage measurement and current measurement input must be 3 phase-neutral. The device will not operate properly if these connections are not done.
b) After the device is energized, it finds connection errors and corrects automatically as the first operation. Phase current should not be equal to zero in order to let the device to detect the connection error. Device detects the connection error according to Active Power direction. Device switches "ON" and "OFF" the 1st step's 3-phase capacitor during the correction of connection errors (Phase sequence error and polarity error of Current Transformer). Device may not correct the connection errors if there are too many instant variations for loads and nonlinear loads (Such as Thyristor or triac controlled frequency inverter, UPS etc.). In this case, user should disconnect the device and restart it to make the same operation. This feature also can also be operated with "turning ON" the "Auto SET" function in "Auto" menu. In this case device corrects the errors and then calculates the capacitor values.
c) After connection errors are corrected; capacitor steps are calculated with turning "ON" the "Auto Setup" function in "Auto" menu (Refer to "Automatic Capacitor Recognition" menu). A 3-phase capacitor has to be connected to 1st step of the device. All steps are measured separately if the program-10 (PS-10) is selected in "Program" menu. In this program (PS-10); single or 3-Phase capacitors can be connected according to requirements of the system in any order. If you let the device calculate the step power values in the previous step, you can skip this part. If one of the other programs is chosen, device measures the 1st steps power value and then calculates the other steps values according to 1st steps value. Device calculates the capacitor values which will be switched "ON" according to selected program and switches "ON" or "OFF" the necessary steps.
d) Connection of a circuit breaker or an automatic fuse is highly recommended between the network and RG3-12C/CS. This circuit breaker must be marked in order to separate them from other breakers.
e) All fuses which are used must be FF type and the current values of the fuses must be 2A or 3A and 6A (Refer to Connection Diagram).
f) The connection to the generator input of the device must be done in a way that the energy comes to the system after the generator connection to the network has been established. Otherwise, the device will be switched to the generator operation for any generator starts including the ones for maintaining purposes.
g) In order make a correct measurement, J type (Fe/Cu-Ni) thermocouple must be connected to "TEMP" terminal.

• For proper operation; 3-Phase, neutral, voltage and current terminals must be connected as shown in the connection diagram. Device does not work properly without 3-phase connection.
  ● After the connection of the current and voltage lines, connect the capacitors to the device. The most important point is connecting a 3-phase capacitor to the first step. Remaining single phase and 3-phase capacitors can be connected to the other steps in any order and power values.
  ● After the connection of capacitor steps; J-Type 0-400 V thermocouple must be connected if temperature measurement function will be used (Temperature measurement feature is optional).
  ● Lastly, computer communication connection must be done.
• Do not energise the device before verifying the connections.
  ● Always connect a 3-phase capacitor to the 1st step.

2.1 Commissioning of RG3-12C/CS

• When RG3-12C/CS is energised for the first time, if the power value of any phase is negative, it switches on&off the first capacitor step automatically to recognize the connection error and records the connections.
  ● Later, automatic setup (Refer to page 6 - Automatic setup) is selected from the menu in order to recognise the connections and connected capacitor steps automatically.
  ● After automatic recognition, RG3-12C/CS checks all capacitor step values. If variable loads exist in the system, these variable loads must be disconnected first and then automatic setup process must be done. Otherwise, power factor controller may not measure capacitor step powers correctly. Capacitor step powers and connection types also can be entered to the power factor controller manually.

(Refer to page 10 - Setting of the capacitor's connection and power values)

● After recognising the capacitor step powers, target Cosφ value is set in order to start the compensation. Factory set value for target Cosφ is ind. 1.000 and Cosφ2 is ind. 0.900

Note: PFC decreases the switching on/off time to 3 seconds in Automatic Setup mode but discharge time is not changed. After the automatic setup process, set values become valid.

2.2 Capacitor Sequence Setting

After the device is energised, it finds connection errors and corrects them automatically. Power values of the capacitor steps are measured automatically according to program selection. If PS-10 program is selected, power values of all capacitor steps are measured (Refer to Program Section). If any other program is selected, device measures first capacitor step value and then calculates other capacitor steps according to the selected program. For this reason, a 3-phase capacitor must be connected to the first step. Single phase and/or 3-phase capacitors can be connected in any order to the other steps. After the device calculates and saves the capacitor values, it will switch them on and off when needed.

3. SETTINGS

3.1 Manual Operation Mode, Automatic Capacitor Recognition Mode and Automatic Connection Control Mode

3.1.a Manuel Operation Mode Setting

RG3-12C/CS has two operating modes which are automatic and manual. The operation mode is chosen by selecting the "Auto Operati" option as on(automatic mode) or off(manual mode). Manual mode is used for test purposes. In this mode, capacitor steps are switched on&off to test relay outputs. In manual mode, capacitor steps are switched on with "SET" button and switched off with "ESC" button. The conditions of the steps can be monitored from the 12 step LEDs on the front panel. C+ LED lights up when a step is switching on and C-LED lights up when a step is switching off. Factory set values for switching on (t-on) and switching off (t-of) time are 10 sec. These values can be changed by the "dELy" menu (Refer to Switching on&off Time for Capacitor Steps and Discharge Time Settings). In manual mode; step numbers, which will be switched on&off, can be programmed in "StEP" menu (Refer to Step Number Setting). Even if manual mode is selected, device switches to automatic mode after 5 minutes continues to operate in this mode.

When automatic mode is selected, AUTO/MAN LED lights up continuously.

When manual mode is selected, AUTO/MAN LED blinks.

Warning: Device warns user by blinking (short ON, long OFF) the LED of the capacitor steps which will be switched on. Also device warns user by blinking (long ON, short OFF) the LED of the capacitor steps which will be switched off.

Numerical values of the parameters are set via buttons in the display. The blinking digit indicates which digit will be set. Numerical value of the related digit is increased or decreased via "UP" or "DOWN" button. To set the next digit, "SET" button is used. To go back to the previous digit, "ESC" button is used.

3 sec.
Press the "SET" button for 3 sec. in order to enter to the menu.

Press "SET" button to set the parameters in "Auto" menu option.

The first setting in this menu is the operation mode(Operati). The operation mode of the device is selected according to this options on or off selection. Press "SET" button to change this setting.

Press "UP" or "DOWN" button. To select the automatic operating mode, choose "on" with "UP" or "DOWN" buttons and press "SET" button. To select the manual operating mode, choose "oF" with "UP" or "DOWN" buttons and press "SET" button.

When the device is energised for the first time, it checks for connection errors. If there is a faulty connection, it corrects this fault in itself. In order for the device to correct a connection fault, 3-phase voltage and current connections of the device must be done.

NOTE: If there are other loads than compensation connected to the system, the device may not find the connection at the first try and may need several tries. However, if the device is unable to complete the automatic connection process step calculation process shouldn't be done.

In order for the calculated capacitor powers to be accurate, the current and voltage transformer ratios have to be entered correctly before the automatic capacitor recognition process. If these ratios are not entered by the user, they will be set as "1" by the device and the capacitor step powers will be calculated according to these values(Refer to page 12-CT and VT Ratio Settings).

After any connection faults are corrected by the device; if "Auto Setup" option is set as "on", the device calculates the capacitor step powers according to the selected program. If 10th program(P-10) is selected, all of the capacitor step powers are measured separately. If any other program is selected, the device measures only the first capacitor step power and then calculates the other step powers according to the selected program(Refer to page 7-Step Number Setting).

NOTE: If the option "on" is selected in the automatic setup menu, the automatic capacitor recognition will start without exiting the menu.

The step powers which are calculated after this process must always be checked.

In Auto Operati menu, choose "Auto Setup" menu by pressing the "UP" button.

The 2nd setting in this menu is the Auto Setup setting. The automatic setup will or will not start according the options "on" or "off" selection. To change this setting, press the SET button.

Select "on" or "of" using the "UP" and "DOWN" buttons (Select "on" for automatic capacitor recognition).

3.1.c Automatic Connection Recognition Mode Setting

This option is used for activating or deactivating the connection recognition mode when the device is energised. It is activated as factory default. In applications with a generator, the voltage and current information may not arrive to the device properly depending on the transfer panels design and delay when the system is switched from generator to the network power. When this transition occurs, the device may find a connection fault. Therefore, it is recommended to turn this option off after the setup is completed.

Select the Auto Setup option in the Auto Operati menu with "DOWN" button.

Connection correction is activated or deactivated depending on the "on" or "off" position of the Auto connection option. To change this setting press the "SET" button.

When Auto connection is "on", the device controls its connection automatically at start-up and corrects any existing measurement input errors. If this option is "of", automatic connection correction is deactivated. Using "UP" ve "DOWN" buttons, select "on" or "of".

If you want to leave the setup menu without making any other changes, press the "ESC" button until "SAVE SET yES" shows on the screen. If you want to save the changes, press the "SET" button. If not, press the "ESC" button.

3.2 Target Cosφ and Target Cosφ2 Value Setting

The device has two target Cosφ values as Cosφ ve Cosφ2.

If there is a voltage between 110-250 VAC present on the generator inputs of the device, the target "Cosφ" set on the device is deactivated and target "Cosφ2" is activated. Then the device starts the compensation according to target Cosφ2. This operation mode continues until the voltage on the generator input is disappeared.

Target Cosφ ve Cosφ2 values may be adjusted between "0,800 ... -0,800" by the user. Negatif values represent Capacitive region and positive values represent Inductive region. RG3-12C/CS tries to match the systems Cosφ to the user defined value. If the need for compensation of a phase is lower than 0,625 times of the capacitor which is connected to that phase, the device doesn't activate or deactivate any steps and stays at NORMAL status. If there aren't any connected capacitors on that phase, the device operates according to one-third(the power for that phase) of the 3-phase capacitor with the lowest power value.

3.2.a Inductive / Capacitive Cosφ and Cosφ2 Setting

Target Cosφ and Cosφ2 values may be entered between "0,800 ... -0,800"

Negative values represent Capacitive Region, positive values represent Inductive

Region

Press the "SET" button to enter the Target Cosφ menu.

Using the "UP/DOWN" buttons, enter a Cosφ value between -0,800 ... 0,800 and press the "SET" button.

Using the "UP/DOWN" buttons, enter to another menu option which you wish to change. If you are not going to change any more settings, press the "ESC" button.

If you want to leave the setup menu without making any other changes, press the "ESC" button until "SAVE SET yES" shows on the screen. If you want to save the changes, press the "SET" button. If not, press the "ESC" button.

3.3 Last Capacitor Step Number Setting

The last capacitor step number is entered between 1-12 for RG3-12C/CS in this menu. For example, if this number is entered as 8, only the steps 1 through 8 will be operated by the device. After this setting is changed, the device must be de-energised and re-energised. If not, the active steps which aren't selected may stay activated.

NOT: When program 10(PS-10) is selected, it is better if the last capacitor step number is set as 12. When program 10 is selected, the activation and deactivation of the steps without a capacitor connected to them is not an issue because with program 10, the connection for these steps can be set as "oFF". The last capacitor step number should be used with the switching sequences other than the 10th.

Press "SET" button for 3 sec. in order to enter to the menu.

Using the "UP/DOWN" buttons, find the step number(StEP) menu option. When the step number setting menu is selected, the STEP LED will turn on.

3.4 Selection of Proper Switching Sequence

RG312C/CS has 10 different program modes which determines the power ratio sequence of the capacitor steps. The switching programs are given in the table.

If the step sequence is selected as in program 02(PS-02), many identical connection components must be used. When a step sequence between the 3rd and the 8th one is selected, less identical connection components will be used. By selecting the 9th connection sequence, different group powers can be achieved. In this sequence connection, the rating of each capacitor step value may exceed that of the first by a maximum amount equal to the preceding capacitor steps value. By using this setting, less capacitors will be used. When the 10th connection sequence is selected, RG3-12C/CS will calculate the capacitor step power values automatically. RG3-12C/CS counts swithing on&off times of all capacitor steps and so only the most necessary step is switched on. Thus, maximum service life time of the system is ensured.

Note: In the 10th program(PS-10), power values and connection types(except the first step) of the single phase capacitor steps(r, s, t, rst, oFF) can be set by user. In Auto setup mode power values of all capacitor steps are measured and connection types of the capacitor steps are detected by the device. In all the connection sequences except the 10th one, only the 1st capacitor step power can be set. All the other capacitor step values are calculated according to the 1st capacitor steps power value.
